A mention on the TV show Rick & Morty led to McDonalds re-introducing Szechuan dipping sauce

"If you’re going to ride a pop culture trend, you’ve got to ride it full send — and that’s why McDonald’s says it’s bringing back its Szechuan dipping sauce. Again.
McDonald’s originally introduced the limited batch of Szechuan sauce in 1998 to coincide with the release of the Disney film “Mulan.” Last fall, the sauce was referenced by Cartoon Network’s popular Adult Swim show, “Rick and Morty,” leading McDonald’s to briefly rerelease the sauce — and leading to full-on riots when the very limited supply ran out.
The fast food chain apologized after the fiasco, saying it had not expected such high demand."
